Abstract:

This paper proposed machining non-developable ruled surface cutter axis vector's analytical method, provided the  analytical method's machining error and compared with the “R offset” flank milling method's error. The results prove  that the prposed melhod can reduce the theoretical errors. Then the blade tool path trajectory was drew by the algorithm with MATLAB software. Finally, NC machining experiments verified the proposed algorithm, the machining results show that the machining errors are within the allowable machining error range and the machining surface quality of impeller is good.
